Title: Liquid fuel combustion equipment
Inventor: OOMUKAE SHIYOUZOU
IPC: F23N1/00
Filed: 1981-04-06
Abstract: PURPOSE:To prevent the abnormal decrease of fuel vaporization and incomplete combustion by a constitution wherein the amount of fuel vaporization is controlled by controlling the amount of electric power to be supplied to an electric heater in a hot air heater using the electric heater and combustion heat as the heat source for fuel vaporization. CONSTITUTION:The temperature detection signls from a suction temperature detecting thermistor 15 and a blowing-off temperature detecting thermistor 16 are inputted to a temperature difference detection amplifier 17 in order to amplify the difference between the tempertures detected with the thermistors 15 and 16 and, after that, to input to a heater current controlling circuit 18 so as to control the amount of electric power to be supplied to the heater 12 by controlling a current controlling element 13. The decrease of the amount of fuel vaporization results the decrease of the difference between the suction temperature 15 and the blowing-off temperature 16. Accordingly, when the decrease of the amount of fuel vaporization occurs, the output from the amplifier 17, which is inputted to the heater current controlling circuit 18, is changed in such a manner as to actuate the current controlling element 13 so as to increase the anount of electric power to be supplied to the heater 12, resulting in increasing the amount of fuel vaporization. Owing to the constitution as mentioned above, the abnormal decrease of fuel vaporization and incomplete combustion can be prevented from occurring.

Title: Ophthalmology diagnostic device
Inventor: AIZU YOSHINAGA
IPC: A61B3/10
Filed: 1989-03-06
Abstract: PURPOSE:To obtain objective measurement data by setting the diameter of a fine circular detection opening to the specified range of each speckle for a speckle pattern to be observed on the setting surface of the fine circular detection opening. CONSTITUTION:The frequency of convergency for a photon correlative function is evaluated quantitatively and the detection opening is made circular based on the condition. Then, the diameter of the detection opening is made (1-5)-fold to the average diameter of the speckle to be detected and accordingly, the almost optimum condition is obtained. As a detection opening 20, the fine circular opening such as a pin hole can be satisfactorily used. For example, when one desired blood vessel 60 is obtained in an enlarged picture and a pin hole 61 having the diameter smaller than the diameter of the blood vessel on this picture is arranged in a part where a picture surface speckle 62 in the blood vessel is fluctuated, the intensity of detection light is changed in correspondence to the crossing of the speckle in the detection opening 20 and a speckle signal can be obtained.

Title: Electromagnetic wave absorber
Inventor: MIYATA SHIGEMORI
IPC: H05K9/00
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To obtain a thin electromagnetic absorber by constituting it, of a soft magnetic material region constituted by dispersing powder composed of soft magnetic metal particles in polymer resin, and of a low permittivity region formed in the soft magnetic material so as to divide it into two or more regions. SOLUTION: Soft magnetic material α is constituted by dispersing soft magnetic metal powder into polymer resin. In the metal powder, powder composed of soft magnetic metal particles exceeds 10% of the rate occupied by a surface layer within 1μm form the particle external surface to the total volume. Low permittivity material βis formed in the material α so as to divide it into two or more regions, and has a relative permittivity lower than 5. Thinner electromagnetic wave absorber is constituted of the material αand the material β, and is obtained by matching the permeability with the permittivity. The soft magnetic material into which metal particle powder is dispersed is divided by a region of low permittivity, and the average permittivity as the whole is decreased, so that the condition to reduce reflectivity is satisfied.  Thereby electromagnetic wave absorber is obtained.
